which month you will be travelling to hk?

Will be damn hot & humid weather 

during my last trip, i brought around 8K HKD.

600 HKD per day seem okay but depend on what you eat.

is always better to bring extra rather then less

6 days 5 night.

1400 is for the motel rent, the rest is for food, transport, night activity, drinking etc etc.

i don't really visit those tourist area but focus more towards rural area like tuen mun, wai chuen village, partly because my local friend had a car, so travelling is easy for me.

but just prepare to walk hell alot, i leg is sore during the entire trip.

if got time, take the mini bus to stanley, the sea view is fantatics and very nice to just sit at the bench relax

Problem with food and travelling, I don't eat much when travelling.

only spend 1500HKD ? i alredi spend 400+HKD juz on groupon hk.....T.T

there are many free aps on smart phone that allow you to simulate your route and tell you how much it will cost. 

there are plenty of good deal at groupon hk ...somemore collection is easy as its opposite Times Square only...big shop....

Include air flight tickets?

Here's my cost for hotel and flights

Flight ticket for 2 - RM720
Hotel stay for 2 (6 days, 5 nights) - RM1.3k

As for food, I'm trying to calculate the base cost now. and might take extra HKD2-3k per person as pocket money to there.

Instax 210 is selling for Rm280 the last time I went there during New Year.

That model I got it for rm230 at a shop in digi mall 2nd floor. December 2012

my friend got a good canon dslr there, cheaper and with package includes 16Gb card, spare battery, tripod and bag
